To all whom it may concern: 1

Be it known that EDGAR P. MULL, a citizen of the United States of America, residing at Toledo, in the county of Lucas and State of Ohio, has invented certain new and.

useful Improvements in W'atei Coolers, of which the following is a specification.

My invention relates to Water coolers and more particularly to the type known as coil coolers. i

The principal object of my invention is to provide a cooler coil of such resiliency for supporting the ice that the coil is not liable to become damaged when afresh cake of ice is placed in the Water cooler, and in contact with the coil.

It is advisable in the so called coil type of coolers to locate the cooler coils at the bottom of the cooler where they do not interfere with the placing of the ice cake inthe cooler. Furthermore when so positioned the ice will rest upon-and always be in contact with the coils and consequently a maximum of refrigeration obtained. However, the

placing, of the cooler coil upon the bottomof the cooler has proven objectionable due to the fact that the coils would frequently become crushed or damaged by being jammed against the bottom of the cooler, particularly where the ice cake slip ed when a fresh cake was being placed in t e cooler. Others have sought to overcome this objection by the use of false bottoms placed above and out of contact with the coils, but as previously stated maximum cooling of the coils can not be had except where the ice is in direct contact with the coils. It is the purpose of the present invention to overcome these disadvantages.

In the accompanying drawings forming part of this application:

Figure is a perspective view partly broken away of an ice cooler showing my invention. I

Referring more particularly to the drawings forming part of this specification, 5 denotes a cooler or ice box comprising spaced side, end and bottom walls 6, having a cork or other suitable insulating filling 7. A

suitable cover 8, seals the top opening 9,

the cooler. q 10, is a water inlet pipe extending through the bottom of the cooler and leading from any suitable source of water supp-1y (not shown). A water outlet pipe or coupling 11, extends through one of the side walls of the cooler, and is connected at its outer end to any suitable faucet 12.

The cooling coil 13, comprises a series of bends or convolutions 14, of progressive height from the bottom coil orbend 15, to the top coil 16. The convolutions or bends preferably are of increasing size from the bottom bend upwardly and preferably more or less concentric but this is'not absolutely necessary, the essential feature being that they are graduated in height in order to provide a resilient seat for the cake of ice 17 To this end preferably only the bottom convolution or bend 15, normally engages the bottom wall of the. cooler, but more than one bend may so engage.

The topconvolution or bend 16, is con nected to the water outlet pipe 11, and the bottom convolution or bend 15, is connected to the inlet pipe 10. A waste pipe 20, the upper end of which is above the horizontal plane of the top convolution or bend 16, of r the cooler for suitable drainage.

In placing the ice in the cooler the former is inserted through the top opening 9, of the cooler, onto the top convolution or bend 16, the convolutions or bends giving in turn until the ice is resiliently supported thereon, all shock and jar being absorbed thereby. The weight of the ice incontact with the convolutions or bends of the cooler coil causes the ice to drop down as the said bends eat into the cake of ice. As the bends become incased in the cake, the former are gradually brought up to the temperature of the ice and in consequence the melting of the ice thereafter becomes very slow.

Having thus described my invention, what I claim as my invention is:

1. A water cooler comprising an ice box having a water inlet and a water outlet, a resilient refrigerating coil connected at opposite ends to said inlet and outlet respectively, said coil having bends or convolucoil, provides tions graduated in height, therbottom most Q evogoee resilient refrigerating coil having bends or I In testimony whereof I aflix my signature convfolutions if graduating height and cirin presence of two witnesses. cum erence t e topmost of said bends connected to the water outlet, and the bottom EDGAR MULL Imost of said bends normally seated on. the Witnesses: v 1
